How does it assist with load testing?

The skill helps generate and execute load testing scripts using industry-standard tools like k6 and Artillery to simulate various traffic patterns and spikes.

Can this skill help with database performance?

Yes, it includes detailed workflows for identifying slow queries using EXPLAIN ANALYZE and detecting N+1 query patterns in various ORMs.

Does it support frontend bundle optimization?

It provides guidance for bundle analysis using tools like Webpack Bundle Analyzer and Next.js Bundle Analyzer to identify and replace heavy dependencies.

Which programming languages are supported by this skill?

The Performance Profiler provides specialized profiling patterns and tool guidance for Node.js, Python, and Go applications.

What is the 'Measure First' rule included in this skill?

It is a methodology that requires establishing a clear performance baseline before making changes to ensure that optimizations provide measurable improvements.
